Mathswatch marked my correct answer wrong, wondered if anyone has got it right

I was doing mathswatch for homework and I got my answer wrong even though I'm pretty sure it was correct. Can anyone check if it's a mistake on my half or if anyone else has solved this question?The size of largest angle in a triangle is 3 times the size of the smallest angle. The third angle is 10˚ more than the smallest angle.Work out the size, in degrees, of each angle in the triangle. You must show your working (let x be the smallest angle). My answer copy pasted: sides of triangle= 180˚first=xsecond= 3xthird= x 10180˚=x (x 10) 3x180˚=5x 10170˚=5xx=170˚/5=34˚first: x=34˚second: 3x= 3×34=102˚third: x 10=34 10=44˚34˚,102˚,44˚ Can anyone help please??

You might want to edit that post and space out the question, because right now my eyes are hurting from looking at it and I can't even begin to get my head around it. Space it out and i'll see what I can figure out :smile:

Looks ok to me (apart form the formatting). Is the first angle the largest, the second the smallest, so swap the first two values in your answer?

You have '+' signs missing in your answer (e.g. ...third = x + 10 ...)
Also, better if units only appear for your answers and not in your working (change 180˚ = ... with 180 = ...)
